Description
Technical field
The present invention relates to mould manufacturing field, more particularly to the grading die stamping process of automobile shock branch pillar support.
Background technology
Sheet Metal Forming Technology traditional at present is the either simplex sequence production taken, and this kind of either simplex sequence production model can not ensure correctly
Strip mode and stable self-feeding production can not be realized, the ability for quickly going out part after hardware and software platform production can not be met, and
Conventional ones technique has the problem of cost is high, process is more, waste production space, greatly reduces production efficiency.
The content of the invention
The applicant is directed to above-mentioned existing issue, has carried out Improvement, there is provided a kind of level of automobile shock branch pillar support
Enter die stamping process, can break through traditional either simplex sequence using the present invention produces, and substantially increases production efficiency.
The technical solution adopted in the present invention is as follows：
A kind of grading die stamping process of automobile shock branch pillar support, comprises the following steps：
The first step：Blanking and punching：After tablet is sent to punching station by feeder, goes out two on tablet by perforating press and determine
Position hole；
Second step：It is punched for the first time：Tablet with positioning hole is subjected to punching trimming for the first time；
3rd step：Second of punching：Tablet with positioning hole is subjected to second of punching section, tablet is formed expansion
Shape；
4th step：Drawing：By the material strip finite element analysis for deploying shape and carry out prestretching and prolong processing；
5th step：Material strip obtained by 4th step is subjected to convex closure shaping, the convex closure R angles among tablet is molded in place；
6th step：Correcting is carried out to tablet by positioning hole, carries out first time finish trimming, the feeding to tablet product both ends
Waste material fine；
7th step：Correcting is carried out to tablet by positioning hole, second of finish trimming is carried out, to two lump waste materials among tablet
Fine；
8th step：Correcting is carried out to tablet by positioning hole, third time finish trimming is carried out, to two lump waste materials at tablet both ends
Fine；
9th step：Tablet after carrying out finish trimming is carried out by flange processing by stripper；
Tenth step：Shaping is carried out to the tablet after flange, makes the abundant plastic deformation of product；
11st step：Positioned by the type face of tablet after shaping and positioning hole, positive punching is carried out to tablet by punch press；
12nd step：Deburring and side punching are carried out to tablet by punch press；
13rd step：Positioned by positioning hole, flange and separation cut are carried out to tablet.
Its further technical scheme is：
In the first step, the positioning hole is circular port.
Beneficial effects of the present invention are as follows：
Present invention process is simple, the production efficiency of product can be improved using present invention process, which not only reduces entirety
The development cost of product, the product time is also substantially reduced, reduce product employment quantity, make floor space and storage area big
It is big to reduce, effectively increase the efficiency of product.
Brief description of the drawings
Fig. 1 is state schematic front view of the product under each step process.
Embodiment
Illustrate the embodiment of the present invention below.
As shown in figure 1, the grading die stamping process of automobile shock branch pillar support comprises the following steps：
The first step：Blanking and punching：Predetermined tablet will be put on autoloader and reach predetermined punching position by feeder, on
For mould in the top dead-centre of lathe, lower mould is on the work top of punch press, and when punch press works, reciprocal fortune is completed from top dead-centre to bottom dead centre
It is dynamic, perforating press is gone out two positioning holes on tablet, the positioning hole is circular port, and it is used for the Global localization of whole material strip,
Then feeder starts automatically by cloth away from feeding is carried out, and stamping machine pressure is 50T in the step.
Second step：It is punched for the first time：Tablet with positioning hole is subjected to punching trimming for the first time, tablet is formed expection
Shape, stamping machine pressure is 91.5T in the step.
3rd step：Second of punching：Tablet with positioning hole is subjected to second of punching section, tablet is formed expansion
Shape, stamping machine pressure is 95T in the step.
4th step：Drawing：By the material strip finite element analysis for deploying shape and carry out prestretching and prolong processing.
5th step：Material strip obtained by 4th step is subjected to convex closure shaping, the convex closure R angles among tablet is molded in place.
6th step：Correcting is carried out to tablet by positioning hole, carries out first time finish trimming, the feeding to tablet product both ends
Waste material fine, stamping machine pressure is 25.4T in the step.
7th step：Correcting is carried out to tablet by positioning hole, second of finish trimming is carried out, to two lump waste materials among tablet
Fine, stamping machine pressure is 47.5T in the step.
8th step：Correcting is carried out to tablet by positioning hole, third time finish trimming is carried out, to two lump waste materials at tablet both ends
Fine, stamping machine pressure is 43.7T in the step.
9th step：Tablet after carrying out finish trimming is carried out by flange processing by stripper.
Tenth step：Shaping is carried out to the tablet after flange, makes the abundant plastic deformation of product.
11st step：Positioned by the type face of tablet after shaping and positioning hole, positive punching is carried out to tablet by punch press, should
Stamping machine pressure is 19.4T in step.
12nd step：Deburring and side punching are carried out to tablet by punch press, stamping machine pressure is 33.9T in the step.
13rd step：Positioned by positioning hole, flange and separation cut are carried out to tablet.
Present invention process is simple, the production efficiency of product can be improved using present invention process, which not only reduces entirety
The development cost of product, also substantially reduce the product time, reduce product employment quantity, stamping machine pressure up to 780T, its
15 times/min drawing velocity can be realized, greatly reduces floor space and storage area, effectively increases the efficiency of product.
Above description is explanation of the invention, is not the restriction to invention, limited range of the present invention is referring to right
